| 中文摘要: |
| 介绍低肩冠比12R22.5无内胎全钢载重子午线轮胎的开发。结果表明：12R22.5轮胎肩冠比小于1.3时，可以满足轮胎轻量化以及降低设计成本的要求；成品轮胎的充气外缘尺寸和强度性能均符合国家标准要求，耐久性能和高速性能满足设计和企业标准要求，静态接地性能和滚动阻力系数满足配套主机厂要求。 |
| 英文摘要: |
| The development of low shoulder crown ratio 12R22.5 tubeless truck and bus radial tire was introduced. The results showed that when the shoulder crown ratio of 12R22.5 tire was less than 1.3，it could meet the requirements of tire lightweight and reduce the design cost. The inflat periphal demention and strength performance of the finished tire met the requirements of the national standards，the durability and high-speed performance met the requirements of the design and enterprise standards，and the static grounding performance and rolling resistance coefficient met the requirements of the supporting OEM. |
